The olive pulp generated during the two-phase processing of the olive oil contains almost 80% (per dry weight) carbohydrates and thus it could be an ideal substrate for the production of energy in the form of ethanol, hydrogen and biogas (methane). Very limited research has been done so far on making value out of this waste. The proposed BIOTROLL project aims at studying the biological treatment of the olive pulp for the production of ethanol and hydrogen, the subsequent anaerobic treatment of the effluent with the simultaneous production of methane and the agricultural re-use of the final residue as soil improving agent and/or fertilizer. Optimisation of the whole process will take place regarding the optimal combination of the different treatment steps that would be most favourable from both the environmental and financial point of view.
